ORVILLE OOOLEY, OF BROGKPORT, NEW YORK, ASSIGNOR TO JOHNSTON HARVESTER COMPANY, OF SAME PLACE.

HARVESTER-RAKE.

SPECIFICATION forming part of Letters Patent No. 225,971, dated March 30, 1880.

Application filed February 20, 1880.

To all whom it may concern Be it known that I, ORVILLE GOOLEY, of Brockport, in the county of Monroe and State of New York, have invented a new and Im- 5 pr( d Will-Trip for Harvester-Rakes; and I do reby declare the following to be a full, clear, and exact description of the same, reference Lein g had to the accompanying drawings, forming part of this specification, in which- Figure l is a side elevation of the standard and trip. Fig. 2 is a horizontal section of the same. Fig. 3 is a detached view, showing the engagement of the gate-latch and the slotted stud. Fig. 418 a perspective view of the drag- 1 bar; and Fig. 5 is a section of the parts for effectingthe adjustment of the standard and shaft.

Similar letters of reference in the accompanying drawings denote the same parts.

This invention relates to that class of bar vester-rakes in which the rake-arms, revolved by a vertical or inclined shaft, are guided by a double cam-track and switch-gate, so as to operate both as reel-arms and rake-arms; and it consists in means for enabling the attendant to open the switch at will and cause the arm to sweep the platform and discharge the gathered grain.

In the drawings, Ais a shelf or bridge of metal applied to the drag-bar or other proper part of the machine, and upon which the standard D D of the cam-track T is supported, as represented in Fig. 1. The standard is bolted to the upturned ends Z) b of a base-plate, B, 3 which carries an arched casting, E, provided with a central boss, 6, stepped in the baseplate, so as to turn when necessary for adjustment. Such casting also affords the step for the Idle-shaft O and the bearing for the lateral shaft F. It is adapted to be turned on its boss 0, for adjusting the Working position of the rakes, by means of screws 6 passing through its ends into curved slots in the baseplate B, as shown. 5 These various parts I do not propose to claim in this case, as they form the subject of a separate application for Letters Patent.

Therake'shaft, rake-arms, cam-track, switchgate, spring S,for throwing the gate open when unlatched, j ointed latch Gr, for locking the gate when closed, slotted adjustable stud H, and master-pinion I are all constructed and operate substantially in the manner described in my patent of January 23, 1877, No. 186,413.

Instead of arranging a small gear-wheel on the stud H to open the gate automatically, as heretofore, I now arrange on the said stud a thin pinion, M, having a number of cam-inclines m on its upper surface, which, when the pinion is in its normal position just clear the. latch, so as not to open the gate,but when the pinion is slid up on the stud come immediately, by the rotation of the pinion, into contact with the latch, thereby raising it, opening the gate, and allowing the arm that is at the time descending to pass on to the lower track and rake off the grain from the harvester-platform. Various expedients may be resorted to for raising the pinion M at will in order to open the gate; but I prefer to employ the device shown immediately beneath the pinion in Fig. 1, which consists of a ring or sleeve, R, slipped upon the stud and held by a pin, 4), inserted into the side of the stud, the lower edge of the ring having a cam formed upon it, so that when the driver, by any suitable means, such as a hand or foot lever arranged near his seat, draws the arm 7' toward him the ring will be raised on the pin, and will lift the pinion and latch, and when the driver releases the ring the spring 8 will restore it to its normal position and allow the pinion to slide down again. Any other known mode of raising a rotating wheel upon its shaft or stud I consider, how ever, to be the equivalent of this construction. If the automatic apparatus described in my former patent be preferred to this the pinion M, formed as here described, may be removed, and the autom atically-operatin g pinions shown in my former patent may be substituted on the stud H, without any other change in the machine, so that the purchaser of any particular harvester may have his machine adapted to either mode of operating the gate, or, by a mere change of the pinion and lifting device, 5 to both modes, if he prefer.

The great advantage of this will-trip arises from the fact that although the driver can, by a movement of his hand or foot, cause any arm to rake off at will, yet he cannot, under any circumstances, cause the switch-gate to I to-each other, the arms can never strike the open in such a manner that the roller on the rake-arm will strike it and injure it; for the driver does not directly raise the latch, but only raises the pinion, which, by its revolution, raises the latch, and the cams on the pinion and cogs by which the pinion is driven are so arranged with relation to each other and to the rake-arms that each one of the cams in will unlatch the gate at exactly the proper moment for the roller of the arm to pass freely through.

In the machine here shown the drivingpinion I has twenty cogs and the rake has five arms, so that four cogs are apportioned to each rake-arm, in which case, by arranging one cam on to each four cogs on the driven wheel, and adjusting the cam and its rake-arm properly opening gate, but will always find it either completely open or completely closed as they approach it. The number of cogs on either wheel or the number of rake-arms or the number of cams can be varied as may be desired, provided the principle of the above-described arrangement and adjustment be adhered to.

I claim as my invention The combination of the cam-pinion M with the rake-shaft and gate-latch, and with mechanism for lifting the said pinion at will in order to open the gate for any arm of the rake, substantially as described.

OBVILLE GOOLEY.
